Vacuum-Filtered MXene/Carbon Nanotube Composite Films for Li-Ion Capacitors.

ABSTRACT: MXene has garnered significant attention for its applications in electrochemical energy storage devices, such as supercapacitors and Li-ion capacitors, owing to its high electrical conductivity and relatively high capacitance/capacity in both aqueous and organic electrolytes. Utilizing its two-dimensional (2D) structure, this study prepared vacuum-filtered MXene/carbon nanotube (MXene/CNT) composite films for Li-ion capacitors. The incorporation of CNTs plays a critical role in mitigating the restacking of MXene flakes and enhancing the structural integrity of the films. The MXene/CNT films were first characterized by using various physicochemical methods and evaluated in electrochemical half-cells. A Li-ion capacitor was subsequently fabricated by using the MXene/CNT-12% film as the negat
